'FIRE-ROLLING MILL.

SPECIFICATION `To all whom it may concern:

Be it known that I, JAMES MUNTON, aeitizen of the United States, residing in Maywood, in the county of Cook and State of Illinois, have invented anew and useful Improvement in rFire-Rolling Mills, of which the following is a specification.

\ operation.

One feature of my present improvementconsists in mounting the guide-rolls, which are adjacent to the main vertical driven roll and to the inside vertical pressure-roll, on later-v` ally-moving slides, which are adjusted or moved out automatically as the tire or ring increases in diameter by means of a slide carryiug two exterior pressure-rolls diametrically opposite the main exterior driven roll. This latter slide is vfurnished with angle grooves or cams, which actuate levers pivoted to the laterally-moving slides upon which the guide-rolls are mounted.

Another feature of my improvement consists in making the guide-rolls and the two exterior pressure-rolls vertically adjustable, so that by adj Listing one or otherof the guiderolls up or down the tendency of the tire or bloom being rolled to climb up may be counteracted and the same caused to run truly in a horizontal plane.

To adapt the machine to roll two or more rings or tires simultaneously, I provide the slide which carries the inside vertical pressure-roll with a vertically-swinging hanger rings or one very wide ring or bloom.

Application met August 5,1889? forming part of Letters Patent No. 416,797, dated December 10, 1889.

seria No. 319,823. (No moda.)

- placed in or taken out of the machine by means of a small hydraulic cylinder or other suitable engine or power.

Another feature of my improvement eon sistsin mounting the inside pressure-roll so that it revolves upon its shaft, the shaft being made non-rotary., By this means I am enabled to .overcome the difficulty arising from the scales dropping down into the bearings of the inside pressure-roll shaft.

Other features of my improvement consist in the novel devices and novel combinations of parts and devices herein shown and described, and more particularly pointed out in the claims.

In the accompanying drawings, which form a part .of this specification, and in which similar letters of reference indicate like parts, Figure l is a plan view of a tire-rolling machine embodying my invention. Fig. 2 is a side elevation. Fig. 3 is a partial central vertical section on line 3 3 of Fig. l. Fig. 4

is a partial horizontal section on line 4 4 of Fig. 2; and Figs. 5 and 6 are vertical crosssections on lines 5 5 and `6 6, respectively, of Fig. l.

In the drawings, A represents the bed or frame of the machine. B is t-he main exterior vertical driven roll; O, the inside vertical pressure-roll; D D, the automatically actuated or adj usted guide-rolls adjacent thereto;

. E, Fig. 4, the horizontal driven edging-roll;

F, the vertical movable or pressure edgingroll, and G G the two exterior pressure-rolls diametrically opposite the main exterior driven roll B.V rlhe roll B or its shaft B is driven from the main driving-shaft I-I by the beveled gears h and h. The horizontal driven edging-roll E or its shaft E' is driven from the driving-shaft I-I by the spur-gears h2 h3 and the sleeve h4, which is splined to the shaft E', so that the said shaft may reciprocate in said sleeve.

The verticalinside pressure-roll C is journaled or revolves loosely on its non-revolving shaft C', which is mounted upon a sliding carriage K, which reciprocates in suitable guides K on the frame of the machine and is actuated by a hydraulic cylinder K2 and piston K3. The slide or carriage K has a bearing 7c for the lowerend of the shaft O and a bearing or support la for the middle portion of t-he shaft, and a pivoted or vertically-movable hanger 7a2, having a bearing or support 7c3 for the upper end of the shaft C. The hanger k2 is preferably pivoted to the slide K, so that .it may swing vertically out of the way of the tire or bloom which is being placed in or taken out of the machine. The pivoted hanger k2 is preferably operated by a hydraulic cylinder L, the piston L of which is connected by links or cables L2 L3 with arms 704 7a4, projecting from the shaft or pivot of the hanger k2. swinging hanger 7a2 may be easily and quickly moved out of the way and replaced inA posi` tion. The shaft C of the roll C may be adj usted vertically up and down by means of a screw c.

The driven edging-roll E' and also the exterior pressure-rolls G G are mounted upon j and carried by a horizontally-moving slide with great trueness and uniformity.

M, which travels in suitable guides IN on the main frame of the machine, and is actuated Vby a hydraulic cylinder N and its piston N.

The sliding carriage M is furnished with cams or inclined grooves m m, in which it pins or rollers o, carried by the laterally-vibrating levers O O, which serve to automatically adjust the guide-rolls D D. Theguiderolls D D are carried by laterally-moving slides P P, which travel in transverse guidesv P P on the main frame of the machine.

The guide-rolls D D are mounted or journaled upon vertically-adjustable slides or blocks Q Q, which slide in suitable guides upon the transverse slides P P. The motion of the levers O O is communicated to the guide-rolls D D 'by means of pivoted links'O O, which are furnished 'with screw-threads and turn-buckles 0 o for purposes of adj ust ment. As the exterior pressure-rolls G G are' carried by the same slide M which through* yits cams m actuates the guide-rolls D D, theV guide-rolls D D will be automatically and continually kept in proper position relativeI to the expanding diameter of the tire' to maintain it of a true circular shape. means I am enabled to roll the tires or rings The movable or edging pressure-roll F is made' conical, and its shaft F', upon which itloosely fits.and revolves, is mounted at Van angle,' preferably substantially as shown, in the' vertical slide R,- so as to compensate ,for the' increased diameter of the tire vat its outeredge and prevent slipping and Iunnecessary friction.

B C. The particular rolls B C which are By this means the vertically- By this shown in the drawings, however, are of a novel construction, the same being designed for the purpose of severing an annular ingot into distinct rings or tires.

To enable me to form the flanges of the tires out of the inside and best portion of the ingot, where the metal is of the most perfect character and free from imperfections, I provide the roll B with annular grooves b, adjacent to the cutter-flange h, so that the flanges m on the two contiguous tires x will both be lformed adjacent to the line on which the annular ingot or ring is severed. The inside or movable roll C may also be provided, if desired, with a cutter-flange c', op-

posite the cutter-flange b. The rolls B C are also furnished With bottom collars b2 c2. The rolls B C may also be furnished with cutter ianges or collars b3 c3, for the purpose of severing a thin annular chip of imperfect metal from the top portion of the annular casting at the same time that it is severed into two or more tires.

In the operation ofthe machine, when the tire or bloom is being rolled outward, or to a larger diameter, `I prefer to roll or force 'the tire outward against the constant pressure of the exterior rolls G G and of the guiderolls D D, so that the expanding tire or ring will itself automatically adjust the position of the rolls G G and D D, and thus 'not only save the labor of the man or men 'heretofore usually employed for adjusting these rolls, but also enable me to roll the tires or rings ol' a true circular form. In this particular method or process of using the machine I ordinarily roll the tire outward against the pressure exerted upon the rolls GG D D or upon their operating-slide M through the'h'ydraulic cylinder andl piston N N- by theac-A cumulator. The pressure of the accumulator, as commonly employed in a'tire-rolling mill, is ordinarily about three hundred and fifty pounds to the square-inch, and this I find to be a suitable degree of pressure to use ordinarily. The degree of pressure on the 'rolls G GAD D,and against :which the tire is rolled outward, should or may be, however, varied materially according to Weight and diameter or strength of the ring'being rolled. The required pressure upon the exterior rollsG G D D may be exerted by anysuit'ab'l'e meansfor example, in tire-mills Where the ordinary accumulator vis not employed the vlpressure may be communicated directly from oneof the pumps to the hydraulic cylinder N. -I prefer to take the pressure from the accumulator, as it affords a Vsteady and'even pressure against which to roll the tire'outward.

In theV drawings, the accumulater'is indicated at T, and t isthe pipe or connection between the accumulatorand the cylinder N. The construction of the accumulator "Well known to those skilled in thea'rtjand it therefore needs no special description. ."As ordinarily constructed it 'consists *simply 'of a large cylinder with a heavily-Weighted pis- IOO IIO

ton or ram. When rolling the tire outward against the pressure of the accumulator, the valve controlling the communication between the accumulator and the cylinder N, and which is indicated at t', Fig. 1, is left open, so that the tire, as it increases in diameter, must force the rolls G G D D to recede against the yielding pressure exerted upon the piston N of the cylinder N. The pressure exerted upon the exterior rolls G G D D by the cylinder and piston N N is of course less than that exerted upon the inside pressureroll C, when the tire is being rolled outward, as otherwise the diameter of the tire would not increase.

It will be understood, of course, that my new or improved mill,`herein shown anddescribed, maybe used in the old method as well as in the new method just above mentioned; or,-in other words, that the position of `the rolls G G and DD may be from time to time adjusted by the operator. The vertical adjustment of the guide-rolls D D is effected by means of adjusting-screws q q, Fig. 6, threadedV into the vertically-movable blocks Q Q, and the vertical adjustment of these guide-rolls G G is eected by means of Y adjusting-screws gg.

By mounting the upper edging-roll F loosely and so as to revolve on its non-revolving shaft F, I obviate the difficulty heretofore experienced of the shaft F getting out of line by reason of unequal wear .in its two bearings, owing to the pressure of the hydraulic cylinder and piston S S thereon.

I do not herein claim the process of rolling tires or rings outward or from a smaller to a larger diameter against the yielding and continuous pressure of exterior rolls which are caused to recede and adjust themselves automatically by the expansion of the tire itself as it increases in diameter, as that forms the subject-matter of my pending application,
